United States Patent 11 Claims. (Cl. 103-103 The present inventiongenerally relates to a pump construction and more particularly to a pumpwhich has a basic unit which may be employed in conjunction with apriming tank as a pump for irrigation purposes such as for pumping waterfrom ponds, creeks, irrigation ditches and other shallow bodies of waterso that the water may be distributed through sprinklers, irrigationtroughs or the like for placing the water on the soil so that it willincrease the productivity thereof. The pump may also be employed for usein a well of any type for pumping water therefrom and discharging thesame with the pump unit adapted to be arranged in multiples if desiredand adapted to be used in small casing type wells or relatively largebore wells.

The primary object of the present invention is to provide a combineddeep well and portable pump incorporating both the features of acentrifugal pump and an axial flow pump in that the centrifugal motionimparted to the material being pumped is partially converted into axialforce by a spiral deflector arrangement which remains stationary whichcooperates with an enclosing casing for guiding the flow of dischargefrom the centrifugal impeller.

Another object of the present invention is to provide a pump inaccordance with the preceeding objects in which the various bearingsappearing therein are lubricated by the water being pumped with a filterarrangement being provided in each bearing or bushing so that any sandor other foreign material entrained in the water being pumped will notflow into the area between the operating shaft and the bushing thuspreventing this type of damage and providing a long wearing and welllubricated arrangement.

A further object of the present invention is to provide a pump inaccordance with the immediately preceding object in which seal means isprovided in each end of the bushing with the seal means being in theform of an O-ring which is forced outwardly into sealing engagement whenthe pump is actually pumping water.

Yet another important feature of the present invention is theprovision-of a pump having a construction which permits it to be used inconjunction with a portable priming tank which may be driven from thepower take-off of a towing tractor whereby the pump may be backed up toshallow water and the movable intake therefor dropped into the water sothat the device will be readily adaptable for this particular use.

Yet another feature of the present invention is to provide a pump whichalso is adapted for insertion into a well pipe casing of slightly largersize with the pump being provided with seal means for sealing engagementwith the casing whereby the area above the pump will be used as a flowpipe.

Still another feature of the invention is the provision of an adapter atthe upper end of the pump assembly for attachment to a flow pipe wherebythe pump assembly may be self-contained and lowered into a large borewell whereby the flow pipe will support the pump and provide thedischarge therefor.

Other objects of the present invention will reside in its extremesimplicity of construction, adaptation for its ice particular uses andits relatively inexpensive manufacturing and maintenance cost.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 10 is a side elevational view illustrating the self-containedunit of the present invention which is inserted into a well with thefiow pipe being attached directly to the pump unit.

While the invention will be described throughout as being adapted forpumping water for irrigation purposes, it is pointed out that water maybe pumped with this pump for any purpose desired and it is also pointedout that the pump may be employed with any type of liquid desired to belifted or otherwise moved and is adapted for other uses for which pumpsare normally employed. The various materials from which the pump isconstructed are optional with the materials being those satisfying therequirements of sound engineering principles. Also, the various sizesand size relationships may vary without departing from the scope of thepresent invention.

Referring now specifically to FIGURE 3 of the drawings, the numeral 10generally designates the basic pump unit of the present invention whichincludes a cylindrical pump barrel or casing 12 having an internal bore14 of constant cross-sectional area extending between end shoulders 16and 18 and internally threaded portions 20 disposed outwardly of theshoulders 16 and 18 respectively.

Disposed adjacent the outer or lower end of the barrel 12 is an annularcollar 22 having a peripheral outwardly extending flange 24 disposed inabutting engagement with the shoulder 18. The flange 24 is held incaptive relation against the shoulder 18 by a threaded adapter 26 havingan internally threaded portion 28 engaged with the screw threads 20whereby removal or" the adapter 26 will permit removal of the annularmember 22. The inner surface of the annular member 22 is provided with alower inclined surface 39 and an upwardly inclined surface 32 joined bysubstantially cylindrical bore 34 which forms a water inlet for the pumpbarrel 12.

Disposed inwardly or above the annular member 22 is a sleeve-like member36 having a peripheral flange 38 resting against the shoulder 16 withthe flange 38 being held against the shoulder 16 by an adapter 40 havingan externally threaded portion 42 for registry with the internalthreaded portion of the barrel 12 outwardly of the shoulder 16. Thelower or outer portion of the sleevelike casing 36 is tapered asindicated by the numeral 44 with the largest diameter being disposedadjacent the annular member 22. The inner end of the sleeve-like member36 is provided with an outwardly inclined surface indicated by thenumeral 46 which is substantially identical to the inclined surface 32on the. annular member 22.

Disposed within the sleeve-like casing 14 is a deflector 48 that istapered complementary to the taper of the internal surface, 44 of thesleeve-like member 36 with the outer surface of the deflector having aplurality of radially extending longitudinal vanes or blades 50 integraltherewith with the vanes or blades 50 being spiraled longitudinally thusforming a deflector for water in a manner described hereinafter. Theouter edge of each of the blades 50 is provided with a shoulder 52adjacent the lower end thereof for engagement with the outer end of thesleeve-like casing 36 as shown in FIGURE 3 for limiting the insertion ofthe deflector 48 into the casing 36 thus preventing binding between thetwo elements and permitting removal of the deflector 48. Thus, inoperation, the deflector 48 becomes rigid with the sleeve casing 36.

The deflector 48 is provided with a longitudinal bore 54 extendingtherethrough with the bore 54 having a bushing or bearing element 56disposed therein for journaling an elongated operating or power shaft 58with the shaft 58 extending beyond both ends of the deflector 48.

The deflector 48 is provided with a plurality of radially extendingapertures. 66.. therein which communicate with an annular recess 62 inthe inner surface of the bore 54 and disposed between the deflector 48and the bushing 56. The bushing 56. is also provided with a plurality ofradial apertures 64 communicating the recess 62 with the interior of thebushing 56 for admitting water into the interior of the bushing 56 forlubricating and cooling the bushing 56 during rotation of the shaft 58.Disposed within the recess 62 is a continuous cylindrical member of felt66 which acts as a strainer for the hibricating water thus straining outany sand or other foreign materials which may be entrained in the water.

Disposed at each end of the bushing or hearing 56 is a sealing collar'70 and 72 respectively with the collars 70 and 72 having a peripheralrecess 74 extending longitudinally thereof which receives the innerportion of an an O-ring 76 which has the outer portion thereof anchoredto the bore 54 by virtue of a peripheral groove in the bore 54. Thelower or outermost seal 70 is provided with a flat headed portion 78while the otherv seal 72 is provided with a conical-shaped head asindicated by the numeral 80 having an O-ring seal 82 therein inengagement with the surface of the shaft 58 thus sealing the shaft 58 inrelation to the member 72 with the O- ring 76 securing the member 72 tothe deflector 48 in sealed relation thus providing an effective seal forholding the lubricating liquid within the support hearing or bushing 56for the shaft 58.

Mounted on the shaft 58 immediately outwardly of th deflector 44 is acentrifugal type impeller 82 secured thereto by a setscrew 84 with theimpeller having an outer ring 86 interconnected with the main body by aplurality of blades 88 which generally extend radially between the bodyand the outer member 86 which is disposed in inclined relationcomplementary to the surface 32 on the annular member 22 with the outerring 86 having a projecting cylindrical collar 9-0 received within thecylindrical portion 34 of the annular member 22 thus forming a guide forrotation of the impeller 82 so that water taken into the cylindricalmember 90 will be engaged by the impeller 88 in such a manner that thewater will be pumped through the impeller 82 into the deflector 48. Theblades 88 may be curved slightly spirally or in any manner whatsoeverfor increasing the effectiveness of the impeller.

Disposed at the upper end of the sleeve casing 36 is a second impeller92 identical in construction to the impeller 82 and being secured to theshaft 58 by virtue of a setscrew 94. The impeller 92 is related to theupper end of the sleeve casing 36 in the same manner as the impeller 82is related to the annular member 22. It is noted that the lower end ofthe adapter 26 may be externally threaded as indicated by the numeral 96for engagement with the internal threads 98 on the adapter 40 so that amultiplicity of the pump units 10 may be disposed one above the other orthe pump units may be disposed in spaced relation by suitable pipe-typeconnection.

Referring now specifically to FIGURES 1-3, it is noted that the adapter40 has a generally cylindrical fitting 100 screw threadedly attachedthereto with the fitting 100 having an externally threaded end 102 andan ex ternally threaded end 104 in engagement with the threads 98 in theadapter 40. Also, the fitting 100 is provided with an annular flange 106which in this instance is employed to retain the inner edge of a collar108 clamped between itself and the outer end of the adapter 40.

In the installation in FIGURES 1-3, the pump unit 10 is inserted into aprimer tank 110 having an end wall 112 with an opening 114 for receivinga portion of the adapter 40 as well as having the outer surface thereofcountersunk for receiving the flange 108. Disposed outwardly of the endwall 112 is a cylindrical housing 116 having a flange 118 disposedagainst the flange 108 with the flanges 118 and 108 being held inabutting sealed relation by an attaching flange 120 secured to the endwall 112 by suitable fastening bolts 122 with a gasket 124 beinginterposed therebetween for adequately sealing the pump unit to thepriming tank. The cylindrical housing 116 is provided with a radiallyextending discharge pipe 126 which may be connected to suitabledischarge conduits 128. A transverse closure plate 130 is provided inthe housing for scaling 011 the water pumping area and this plate 130 isprovided with a support sleeve 132 having radial apertures 134, a feltfilter 136 inwardly thereof and disposed in a recess together with abushing 138 having apertures 140 for communicating the interior surfaceof the bushing 138 with water for lubricating the shaft 58. A packingnut 142 is provided in the outer end of the sleeve 132 with suitablepacking material 144 disposed inwardly thereof for compression by thenut 142 for sealing engagement with the shaft 58. The cylindricalhousing 116 outwardly of the transverse plate 130 is provided withdiametrically opposed enlarged openings 146 for providing access to thepacking nut 142 and the outer end of the housing 116 is provided with atransverse plate 148 having a support sleeve 150 therein together withhearing elements of the thrust type which are generally designated bythe numeral 152 and which may be of any suitable construction.

The tank 110 is provided with an inlet adapter 154 having a tangentiallyextending fitting 156 together with a rearwardly extending inlet pipe158 which may be provided with any suitable strainer or similarmechanism for straining out enlarged foreign objects from the Waterbeing pumped. The connection between the member 156 and the adapter 154is of the swivel type such as would be provided by employing a pair ofO-rings therebetween to permit raising and lowering of the inlet pipe158 in substantially a vertical plane. Any suitable mechanism may beprovided for raising and holding the pipe 158 in a vertical elevatedposition.

The tank 110 is mounted on a portable framework 160 have ground engagingwheels 162 and a forwardly extending tongue 164 which may be connectedto a drawbar of a towing tractor which is generally designated by thenumeral 166. Also, the outer end of the shaft 58 may be provided with auniversal coupling 168 for connection with a telescopic drive shaft 170which may be connected through a universal joint 172 to the powertake-off shaft 174 of the tractor 166 for driving the pump unit 10 inthis particular case.

Referring now specifically to FIGURE 5, it is noted that the pump unit10 is mounted in a well casing 176 with the operating rod 58 extendingabove the hollow housing 116 and terminating in a \'-belt pulley 178which may be connected with any suitable power source for driving thepump unit 10'. The pump unit 10' is identical to the pump unit 10 exceptfor the differences shown specifically in FIGURE 6 and for the additionof a supporting and bearing construction for the shaft 58' with thisstructure being generally designated by the numeral 180 which isdisposed in vertically spaced relation to the pump unit 10'.

Referring specifically to FIGURE 6, it is noted that a collar 182 isscrew threaded onto the threaded end 102' of the fitting 100'. Themember 182 is provided with an outwardly extending flange 184 at itslower end which receives and clamps an inwardly extending flange 186 ona generally cylindrical sealing gasket 138 made of leather or similargasket material with the upper edge of the sealing gasket 188 beingfeathered as indicated by the numeral 190 whereby water engaging thefeathered edge and between the gasket 190 and the member 182 will urgethe gasket 180 outwardly into engagement with the casing 176 thussealing the pump unit so that the carrier of the casing above the pumpunit will act as a flow pipe for the water pumped by the pump unit.Other than this addition, the pump units in FIGURE and FIGURE 3 areidentical. It is also pointed out that the flange 108 has been removedfrom between the fitting 100 and the adapter 40 in the construction ofFIGURE 5 since this flange is not employed in this orientation with theflange being removed and the sealing gasket 188 and the cylindricalmember 182 fitted thereon. The member 182 is also internally threaded asindicated by numeral 192 for permitting a multiplicity of the pump unitsto be hooked together in tandem relation.

Referring now specifically to FIGURES 7 and 8, the supporting andbearing mechanism 180 for the shaft 58 is set forth as including acylindrical sleeve 194 having a pair of diametrically opposed radialsleeves 196 formed thereon for slidably receiving an inwardly extendingprojection 198 on an arcuate brake shoe 200 having friction producingmaterial 202 on the outer surface thereof. A compression coil spring 204encircles each of the sleeves 196 for urging the brake shoe outwardlyinto engagement with the casing 176 for preventing rotation of thesleeve 194 and also providing support for the sleeve 194.

The sleeve 194 is provided with a central bore 204 having a recess 206therein for receiving a felt filter 208 with the bore 204 receiving acylindrical bushing 210. The sleeve 194 is provided with radiallyextending apertures 212 communicating with the recess 206 and thebushing 210 is provided with apertures 214 for supplying lubricatingliquid to the outer surface of the shaft 58 for lubricating the same.The outer ends of the sleeve 194 are each provided with a sealing member216 having an O-ring 218 between the sealing cap 216 and the bushing 194and also an O-ring 220 between the shaft 58' and the sealing cap 216.Each of the sealing caps 216 are disposed adjacent a collar 222 securedto the shaft 58 by a setscrew 222. If desirable, the flat ends of thesealing caps 216 may be altered to any suitable shape such as the shapeof the sealing cap 72 in the construction of FIGURE 3 with the collarhaving a complementary bearing surface for centralizing the elements andmaintaining a contact therebetween.

The construction in FIGURE 10 is substantially the same as that employedin the construction of FIGURE 5 with the exception that the sealinggasket 188 has been eliminated and the pump unit designated generally bythe numeral 10" may be disposed in a well bore 224 of any diameter withthere being no contact between the pump unit 10" and the well bore. Inthis construction, the cylindrical member 182 is attached directly to aflow pipe 226 which extends upwardly and is attached to the housing 116"by attaching flanges 228. In this installation, there is no need and noutility for the sealing gasket 188 and this may be eliminated or if itis desirable, may be left in position with this gasket then beinginoperative. This enables the pump unit 10" to be employed with largebore wells either of the shallow well type or of the deep well typehaving a relatively large bore wherein it would not be feasible toprovide a pump of that diameter. This also enables the pump to beemployed with well casings of different diameters with the pump unitbeing supported from the flow pipe 26 with the casing or housing 116"being supported by any suitable mechanism or supporting base, thedetails of which are not shown.

The suction pipe 158 is provided with a strainer and a foot valveassembly 159 and an eye 157 for engagement with a cable 155 entrainedover a hand operated Winch 153 that is supported on an A-frame 151.

The operation of the unit will appear self-evident. Water enters thecentral area of the impeller 82 and is caused to move radially andaxially outwardly and inwardly by the spirally curved blades 88 on theimpeller. The depending ends of the blades or vanes 50 of the deflectorform a socket for receiving the upper end of the impeller 82 in closeproximity thereto for receiving the water therefrom. The spiralcurvature of the blades or vanes 50 causes the rotational andcentrifugal motion of the water to be converted into axial force thuscausing the water to flow substantially axially along the sleeve casing36 at which time it is picked up by the second impeller and additionalrotary movement given thereto which will assist in the discharge of thewater from the outlet conduit 126. By employing a multiplicity of theunits, the desired pressure and lift may be obtained.

The present application is a refiling of the application of Ethridge F.Ogles, Serial No. 661,395, filed May 24, 1957, for Combination Deep Welland Portable Irrigation Pump.
